Just when you thought the world was without hope, scientists have discovered that kangaroo farts could help stop global warming. 
"Thanks to special bacteria in their stomachs, kangaroo flatulence contains no methane and scientists want to transfer that bacteria to cattle and sheep who emit large quantities of the harmful gas."
Maybe they'll come up with a new law that requires factories and SUV-drivers to own a certain number of kangaroos to offset their carbon emissions.  With headlines like this, anything's possible. 

Update (2007-12-07 11:44am):  One thing I've been thinking about since I first wrote this is how the scientists made this discovery in the first place.  I can't decide if "animal fart tester" is a good profession.  On the one hand, you're going around capturing animals' farts in jars so you can test their chemical structure in a lab.  On the other hand, you get to tell people you're an animal fart tester.  I'd imagine that would supply an endless amount of stimulating conversation at social gatherings. #nature
